Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more specifically, to a turnover box cleaning machine. Background Technology

[0002] Tableware turnover boxes are essential logistics containers used by the catering industry, institutional canteens, and tableware disinfection service companies for collecting, transporting, and storing tableware. After use, the inside and outside of these boxes accumulate a large amount of food residue, grease, and microorganisms, necessitating a rigorous cleaning and disinfection process before reuse. Tableware turnover box cleaning machines are the key equipment for automating this cleaning process.

[0003] A typical tableware turnover box cleaning machine usually includes a box body, conveyor belt mechanism, high-pressure spray system, water circulation filtration system, and drying system. Its workflow is as follows: the turnover boxes to be cleaned are conveyed by the conveyor belt, passing through pre-rinsing, main cleaning, rinsing, disinfection, and drying stations in sequence. The main cleaning and rinsing stations rely on high-pressure water pumps to generate strong water flow, which sprays the turnover boxes from all directions with high intensity through nozzles set at multiple angles to ensure thorough removal of stains.

[0004] However, a significant technical flaw exists in the aforementioned cleaning process, particularly during the high-pressure spraying stage of the main cleaning and rinsing. When the high-pressure water jet impacts the bottom and inner cavity of the turnover box vertically or obliquely upwards, it generates a tremendous upward force. This upward impact can easily lift the lightweight plastic turnover box from the conveyor belt's support surface, causing it to detach from the conveyor belt, shift, tip over, or even jam the equipment. This not only interrupts the cleaning process and affects the overall production line's efficiency but can also cause mechanical damage to the turnover box and the equipment itself, increasing maintenance costs and operational risks.

[0005] To address this issue, existing technologies typically employ simple rigid pressure bars or baffles spanning the conveyor belt, attempting to limit the movement of the turnover boxes through physical obstruction. However, these structures have significant drawbacks: First, their rigid contact easily generates considerable friction and collision noise when pressing down on the boxes, potentially scratching or abrading the turnover box surface; second, they lack adaptability, failing to adequately handle turnover boxes of different sizes, either resulting in excessively large gaps causing limit failure or excessive tightness leading to poor conveying. Utility Model Content

[0006] To overcome at least one of the defects in the prior art, this utility model provides a turnover box cleaning machine, which effectively restricts the turnover box from jumping under high pressure washing by setting a special limiting structure, avoiding damage to the equipment and being suitable for turnover boxes of various heights.

[0007] The technical solution adopted by this utility model is as follows: a turnover box cleaning machine is provided, including a frame, and a flow channel for turnover boxes to pass through is provided in the frame. The flow channel is divided into a main washing area, a rinsing area and a drying area along its length. The bottom of the flow channel is provided with a conveyor belt for driving the turnover boxes to pass through the main washing area, the rinsing area and the drying area in sequence. The upper part of the flow channel is provided with a limiting component extending along its length to prevent the turnover boxes from falling off the conveyor belt during the flow. The limiting component includes multiple limiting pressure strips that extend along the length of the frame and can be elastically deformed, and an adjusting component for adjusting the height of the limiting pressure strips.

[0008] Compared with the prior art, the turnover box cleaning machine of this utility model has the following advantages: In the structure of this utility model's turnover box cleaning machine, a limiting pressure strip extending along the length of the turnover box flow channel on the frame is set, and the height of the limiting pressure strip can be adaptively adjusted according to the height of the turnover box. According to the height of the turnover box, the limiting pressure strip is adjusted to the corresponding height position by adjusting the adjusting component. During the movement of the turnover box, the limiting pressure strip is located directly above it and maintains an appropriate height difference. When the high-pressure rinsing water impacts the turnover box, due to the limiting effect of the limiting pressure strip, the turnover box will not be pushed out and detached from the conveyor belt, ensuring smooth passage through each cleaning area. In addition, the limiting pressure strip in this structure is an elastic structure, which can effectively prevent the upper surface of the turnover box from colliding with metal parts or hard materials to generate noise, and protect the upper surface of the turnover box from damage.

[0009] Furthermore, the limiting component also includes a positioning frame, the limiting pressure strip is disposed on the lower end face of the positioning frame, and a plurality of support arms are connected to the positioning frame at intervals along its length direction. The upper end of each support arm is rotatably connected to the frame, and the lower end is hinged to the positioning frame (3). The adjusting component is used to drive the positioning frame to swing around the upper end of each support arm to realize the height adjustment of the limiting pressure strip.

[0010] Furthermore, the positioning frame includes two supporting crossbars extending along the length of the frame and located on both sides of the width of the frame. Multiple fixed longitudinal bars are connected between the two supporting crossbars and spaced apart along their length. Each fixed longitudinal bar has a slot at its lower end, and multiple limiting pressure strips are respectively engaged in the corresponding slots.

[0011] Furthermore, the adjusting component includes a fixed plate connected to the frame and near one end of the flow channel. The frame is provided with a first rotating shaft extending in its width direction and a linkage plate that can rotate around the axis of the first rotating shaft. One end of the linkage plate is hinged to one end of the positioning frame, and the other end of the linkage plate is limited and engaged with the fixed plate.

[0012] Furthermore, the linkage plate is an arc-shaped plate. One end of the arc-shaped plate near the positioning frame is provided with a connecting block extending inward toward the center. The connecting block has a mounting hole at a position coinciding with the center of the arc-shaped plate. The arc-shaped plate is rotatably connected to the first rotating shaft through the mounting hole. The arc-shaped plate has multiple positioning holes circumferentially distributed with the center of the mounting hole as the center. The fixing plate is provided with positioning pins that match the positioning holes.

[0013] As an improvement, the arc-shaped plate is located inside the fixed plate, and a pull rod is provided on the outside of the fixed plate. One end of the pull rod is movably inserted through the fixed plate along the width direction of the frame. The positioning pin is connected to the pull rod, and an elastic reset member is provided between the pull rod and the fixed plate to drive the positioning pin to always have a tendency to move towards the positioning hole.

[0014] In a further improvement, there are two arc-shaped plates, which are located on opposite sides of the frame in the width direction, and a fixing rod connects the two arc-shaped plates.

[0015] In a further improvement, a lever is provided at the end of the arc-shaped plate away from the limiting pressure net.

[0016] In a further improvement, each of the support arms includes two support plates symmetrically arranged along the width direction of the frame. The frame is provided with a plurality of second rotating shafts extending along its width direction. The upper ends of any two symmetrical support plates are rotatably connected to the corresponding second rotating shafts, and the lower ends are respectively hinged to both sides of the positioning frame in the width direction.

[0017] In an improved version, two arbitrarily symmetrical support plates are connected by a fixed connecting rod.

[0018] Other improvements and advantages of this invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and drawings. Attached Figure Description

[0021] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0022] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figures 1-5 As shown in the figure, this application discloses a turnover box cleaning machine, including a frame 1. The frame 1 has a flow channel for turnover boxes to pass through. The flow channel is divided into a main washing area, a rinsing area, and a drying area along its length. The bottom of the flow channel is equipped with a conveyor belt (not shown in the figure) to drive the turnover boxes through the main washing area, rinsing area, and drying area in sequence. More specifically in this embodiment, the frame 1 is assembled from multiple modules, each module having an independent function. For example, there is a main washing module with a main washing function, a rinsing module with a rinsing function, and a drying module with a drying function. Each module is an independent frame 1, which can be assembled according to actual applications. Each module has a corresponding box at its upper end, and the two ends of the box are open. Therefore, when multiple modules are connected and assembled head to head, the multiple boxes form an elongated channel, i.e., the flow channel.

[0025] In some embodiments, the drying module can be further subdivided into an air-drying module with an air knife mechanism and a drying module with a heating function.

[0026] In addition, to ensure the stability of the turnover boxes during the circulation process, a limiting component extending along the length of the circulation channel is provided at the upper part of the circulation channel to prevent the turnover boxes from detaching from the conveyor belt during circulation. The limiting component includes multiple elastically deformable limiting strips 2 extending along the length of the frame 1 and an adjusting component for adjusting the height of the limiting strips 2. In this structure, the limiting strips 2 are usually made of rubber or plastic. In practical applications, the limiting strips 2 are adjusted to the corresponding height position according to the height of the turnover box. During the movement of the turnover box, the limiting strips 2 are located directly above it and maintain an appropriate height difference. When the high-pressure rinsing water impacts the turnover box, due to the limiting effect of the limiting strips 2, the turnover box will not be pushed out of the conveyor belt, ensuring smooth passage through each cleaning area.

[0027] More specifically, in this embodiment, as a preferred structural form, please refer to the appendix. Figure 3 The limiting component also includes a positioning frame 3, which is usually made of metal. The limiting pressure strip 2 is set on the lower end face of the positioning frame 3. It is necessary to ensure that the lower end face of the limiting pressure strip 2 protrudes from the lower end face of the positioning frame 3. This way, when the turnover box is lifted by water pressure during movement, its upper end face will only contact the limiting pressure strip 2 and will not contact the metal frame, thus avoiding scratches on the upper surface of the turnover box.

[0028] On another aspect, in the above structure, multiple support arms 4 are connected to the positioning frame 3 at intervals along its length. The upper end of each support arm 4 is rotatably connected to the frame 1, and the lower end is hinged to the positioning frame 3. The adjusting component is used to drive the positioning frame 3 to swing around the upper end of each support arm 4 so as to realize the height adjustment of the limiting pressure strip 2.

[0029] In this embodiment, the positioning frame 3 includes two supporting crossbars 301 extending along the length of the frame 1 and located on both sides of the width of the frame 1. Multiple fixed longitudinal bars 302, spaced apart along their length, are connected between the two supporting crossbars 301. Each fixed longitudinal bar 302 has a slot at its lower end, and multiple limiting strips 2 are respectively fitted into the corresponding slots. In this structure, the limiting strips 2 are connected by a snap-fit ​​mechanism, facilitating subsequent disassembly and replacement.

[0030] For others, see Appendix Figure 4 and 5The adjusting component includes a fixed plate 5 connected to the frame 1 and near one end of the flow channel. The fixed plate 5 is provided with a first rotating shaft 6 extending along the width direction of the frame 1 and a linkage plate that can rotate around the axis of the first rotating shaft 6. One end of the linkage plate is hinged to one end of the positioning frame 3, and the other end of the linkage plate is limited to the fixed plate 5. That is, when the linkage plate rotates to the required position, it can be limited by the limiting structure with the fixed plate 5.

[0031] Preferably, in this embodiment, the linkage plate is an arc-shaped plate 7. The arc-shaped plate 7 has a connecting block 8 extending inward toward the center at one end near the positioning frame 3. The connecting block 8 has a mounting hole at a position coinciding with the center of the arc-shaped plate 7. The arc-shaped plate 7 is rotatably connected to the first rotating shaft 6 through the mounting hole. Furthermore, the arc-shaped plate 7 has multiple positioning holes 9 circumferentially distributed with the center of the mounting hole as the center. The fixing plate 5 has positioning pins 10 that match the positioning holes 9. When it is necessary to adjust the height of the limiting pressure strip 2, the positioning pins 10 are first pulled out from the corresponding positioning holes 9, the arc-shaped plate 7 is rotated, and the entire positioning frame 3 is swung horizontally until the height is adjusted to the required position. Then, the positioning pins 10 are re-inserted into the corresponding positioning holes 9.

[0032] In this embodiment, the arc-shaped plate 7 is located inside the fixed plate 5, and a pull rod 11 is provided on the outer side of the fixed plate 5. One end of the pull rod 11 is movably inserted through the fixed plate 5 along the width direction of the frame 1. A positioning pin 10 is connected to the pull rod 11, and an elastic reset member (not shown in the figure) is provided between the pull rod 11 and the fixed plate 5 to drive the positioning pin 10 to always have a tendency to move towards the positioning hole 9. In this structure, a mounting hole is provided on the fixed plate 5, and the end of the pull rod 11 near the center of the frame 1 (the inner end) can slide through the mounting hole. The end of the pull rod 11 near the arc-shaped plate 7 is connected to a limiting protrusion ring 14, and the elastic reset member is located between the limiting protrusion ring 14 and the fixed plate 5. See Appendix Figure 5 A pin plate 16 is provided on the side of the fixed plate 5 away from the arc-shaped plate 7. The pin plate 16 is fixedly connected to the outer end of the pull rod 11. One end of the positioning pin 10 is fixed to the pin plate 16, and the other end can slide through the fixed plate 5 to be inserted into the positioning hole 9 at the corresponding position on the arc-shaped plate 7 for positioning and limiting. Specifically, a ball head is provided at the outer end of the pull rod 11 in this structure for easy operation.

[0033] To ensure positioning stability, in some other embodiments, two positioning pins 10 can be provided on the pin plate 16, that is, when the arc-shaped plate 7 rotates to the required position, two positioning pins 10 are simultaneously inserted into the two positioning holes 9.

[0034] Preferably, the elastic reset component is a body spring, which is fitted onto the outside of the inner end of the pull rod 11. Both ends of the spring abut against the limiting protrusion 14 and the inner wall of the fixing plate 5, respectively. Under normal conditions, the positioning pin 10 at the bottom inner end of the pull rod 11 is always extended and positioned under the action of the spring. When adjustment is required, the pull rod 11 is pulled outwards, compressing the spring. After the arc-shaped plate 7 rotates to the set position, the pull rod 11 is released, and under the action of the spring, the pull rod 11 resets towards the inside of the frame 1, causing the positioning pin 10 to be inserted into the corresponding positioning hole 9. This spring not only has a reset function but also ensures that the positioning pin 10 does not easily disengage from the positioning hole 9, ensuring the stability of the entire limiting assembly.

[0035] In this embodiment, there are two arc-shaped plates 7, which are located on both sides of the width direction of the frame 1, and a first fixing rod 12 is connected between the two arc-shaped plates 7. That is, the two arc-shaped plates 7 can rotate synchronously around the first rotating shaft 6 through the first fixing rod 12, so that the positioning frame 3 is more stable when adjusting the height.

[0036] Additionally, a lever 13 is provided at the end of each arc-shaped plate 7 away from the limiting pressure strip 2, and an adjusting crossbar 15 is provided between the two levers 13. The operator can manually turn the adjusting crossbar 15 to drive the two arc-shaped plates 7 to rotate synchronously, thereby adjusting the height of the positioning frame 3. This operation is convenient and less strenuous.

[0037] See appendix for further details. Figure 2 Each support arm 4 includes two support plates 401 symmetrically arranged along the width direction of the frame 1. The frame 1 is provided with multiple second rotating shafts 402 extending along its width direction. The upper ends of any two symmetrical support plates 401 are rotatably connected to the corresponding second rotating shafts 402, and the lower ends are respectively hinged to both sides of the positioning frame 3 in the width direction. More specifically, a second fixing rod 403 connects any two symmetrical support plates 401.
